My father remarried, and I would never associate his wife with the word mother.......in my opinion, just like a birth mother, i dont think its a right or obligation, its a title a person must earn. to the majority of mothers its a natural behaviour to be a mother to their child. In a stepmother situation where there is no legal adoption, i believe a stepmother is obliged to earn the title just like a birth mother and not instantly thing they are now "in charge" of a child just cause they married the childs father...and vice versa.......just like earning someones respect. but this is law so what i have said doesnt make a difference, i am just saying this from experience with my fathers wife who has constantly has used me as a way to argue with my father, and i didnt see my father for 13 years cause i moved overseas with my mother.... she has put down my family and has manipulated my father against me at times, i do not think she deserves the title of mother in any respect, im 21 now, and didnt see my father till i was 15, i have been hurt by her words and behaviour towards me, my father is hopeless in this situation. i did nothing to provoke her, it all started when i flew to the USA to see my father in so many years, i dont know whether she was threatened by me, or jealous of my fathers attention.
If u want to be more than a stepmother and have a motherly involvement in the childs life, u have every right as long as u earn that childs trust, its not an easy situation for any child, at any age, even at 21 i am hurt by her words and actions.
